PURPOSE: An apparatus for re-gasifying LNG(Liquefied Natural Gas) is provided to solve problems about seawater environmental regulation and corrosion due to the seawater by not using the seawater to re-gasify. CONSTITUTION: An apparatus for re-gasifying LNG comprises a re-gasifying line(101), a first circulation line(102), a second circulation line(103), a first heat exchanger(110), a second heat exchanger(120), a third heat exchanger(130), and a clean water heater(150). The re-gasifying line is extended from a LNG storage tank to a demand location. The first circulation line is crossed with the re-gasifying line and circulates heating medium fluid. The first circulation line is crossed with the re-gasifying line and the first circulation line and circulates clean water. The first heat exchanger is installed in a crossed position of the re-gasifying line and the first circulation line and heat-exchanges LNG with the heating medium fluid to re-gasify to natural gas. The second heat exchanger is installed in a crossed position of the re-gasifying line and the second circulation line and heat-exchanges the natural gas re-gasified in the first heat exchanger with the clean water to heat. The third heat exchanger is installed in a crossed position of the first circulation line and the second circulation line and heat-exchanges the heating medium fluid passing through the first heat exchanger and the clean water passing through the second heat exchanger to heat the heating medium fluid. |
